Survey on the amount of covered deposits held on 30 June 2026
AI Analysis
CSSF-CPDI 26/51 announces the **regular CPDI/Fonds de garantie des dépôts Luxembourg (FGDL) survey of covered deposits as at 30 June 2026**, to be completed by Luxembourg FGDL member institutions. This quarterly data collection feeds directly into the risk-based, ex‑ante contribution methodology under the deposit guarantee framework and is operationally important for prudential planning, reporting controls, and funding of the FGDL.
Key dates
30 June 2026 Deadline
– Reference date for the covered deposits snapshot; all figures in the survey must reflect the amount of covered deposits outstanding at close of business on this date
Early July 2026 (TBD by CSSF circular text and technical annex)
– Expected opening of the reporting window for uploading the 30 June 2026 covered deposits survey via CSSF eDesk or other specified channels, in line with the timetable used in prior CPDI surveys
Mid–Late July 2026 (TBD by CSSF/CSSI reporting instructions)
– Likely cut-off date for submission of the 30 June 2026 survey, consistent with prior CPDI quarterly survey practices that require prompt post‑quarter reporting for FGDL purposes
Suggested considerations
Apply the EUR 100,000 coverage cap per depositor for the survey and ensure that non‑eligible deposits (such as certain financial sector deposits or specific categories excluded under the 2015 Law) are correctly filtered out of the covered deposits figures.
Reconcile the 30 June 2026 covered deposits data with internal finance, risk, and regulatory reporting systems to ensure consistency with other prudential data and FGDL contribution calculations.
Arrange for the survey report to be reviewed and formally approved by the institution’s governing body or the designated senior manager responsible for deposit guarantee scheme reporting, documenting the approval and any key assumptions or methodological choices.
Submit the completed 30 June 2026 covered deposits survey through the CSSF eDesk platform or other specified reporting channel within the deadline set by CSSF-CPDI 26/51 and any accompanying CPDI instructions.
Retain detailed working papers, data extracts, and methodology documentation supporting the 30 June 2026 survey in order to evidence compliance to CSSF, facilitate internal audit review, and support future FGDL ex‑ante contribution calculations.
What changed

The circular reaffirms that data reported for the survey feed into the risk‑based ex‑ante contribution mechanism set out in CPDI circulars on FGDL contributions (e.g.
Compliance impact
Non-compliance with the 30 June 2026 covered deposits survey (late, incomplete, or inaccurate reporting) can trigger supervisory follow-up by the CSSF, impact the calculation of FGDL ex-ante contributions, and expose institutions to enforcement measures or reputational risk for weaknesses in deposit guarantee scheme reporting. Because covered deposits data underpin the adequacy of the deposit guarantee fund, supervisory scrutiny of data quality and governance over this survey is likely to be high.

Application of the Guidelines of the European Banking Authority on ancillary services undertakings specifying the criteria for the identification of activities referred to in Article 4(1)(18) of Regulation (EU) No 575/2013 (EBA/GL/2026/01)
AI Analysis
Key dates
22 June 2026
- Circular CSSF 26/913 is published and the CSSF confirms application of EBA/GL/2026/01
TBD (effective date not stated in the publication)
- Firms should apply the CSSF’s expectations from the date the circular becomes applicable, if that date is specified in the full circular text or accompanying CSSF notice
TBD (implementation date not stated in the publication)
- Affected firms should complete internal perimeter reviews and any resulting governance or reporting updates by the first supervisory reporting cycle after application
Suggested considerations
Review all group entities and business lines to identify activities that may fall within the definition of an ancillary services undertaking under Article 4(1)(18) CRR.
Document a formal assessment methodology for classifying activities against the EBA/GL/2026/01 criteria.
Reconfirm the prudential consolidation perimeter and ensure all ancillary service entities are correctly included or excluded, with the reasoning retained for supervisory review.
Update legal entity inventories, regulatory mapping, and governance documents so they align with the CSSF’s adopted EBA framework.
Test whether existing internal reporting, risk management, and control frameworks capture any newly identified ancillary services undertakings.
What changed
- The CSSF has formally applied the EBA Guidelines on ancillary services undertakings specified in EBA/GL/2026/01 for identifying activities under Article 4(1)(18) of Regulation (EU) No 575/2013.
Firms must assess whether a non-bank activity or group entity qualifies as an ancillary services undertaking under the EBA criteria, rather than relying on internal labels or informal business...
The regulatory perimeter analysis now needs to consider whether relevant activities are performed within a banking group in a way that affects prudential consolidation and supervisory treatment.
Institutions should expect the CSSF to use the EBA framework as the benchmark for determining whether an activity is sufficiently connected to banking support functions to fall within the ancillary...
Compliance evidence will need to show a documented, reproducible assessment of each potentially relevant activity against the EBA identification criteria.
Compliance impact
The compliance impact is moderate to high because the main risk is misclassification of entities or activities within the prudential perimeter, which can lead to supervisory findings, reporting errors, or consolidation issues. Non-compliance may result in CSSF remediation expectations, delayed approvals, or corrective supervisory action if a firm’s entity mapping is inconsistent with the EBA criteria.
EBA report on simplifying EU prudential and resolution framework stacking orders. Informational publication addressing regulatory complexity reduction while maintaining resilience standards. Primarily impacts banks' capital requirements and resolution frameworks.
The CSSF has launched a consultation on national **Guidance on Money Market Fund Weekly Liquid Asset (WLA) Levels**, aligned with the European Commission’s 2026 MMF report, which defines “market resilience” WLA benchmarks above the MMFR regulatory minimums. This signals a move toward **enhanced liquidity risk management and intensified supervisory scrutiny** for Luxembourg‑authorised MMFs whose WLA levels fall below these resilience benchmarks, even if they remain above the legal minimum.
Key dates
11 May 2026
– European Commission publishes its report on the adequacy of the MMFR and FAQs, identifying market resilience WLA levels for VNAV and CNAV/LVNAV MMFs
15 May 2026
– CSSF informs the market of the Commission’s MMF report and FAQs and flags the identified WLA “market resilience” benchmarks
8 June 2026
– CSSF publishes the communiqué launching the consultation on “Guidance on Money Market Fund Weekly Liquid Asset Levels.”
3 August 2026 Deadline
– Deadline for stakeholders to submit electronic responses on the consultation to the CSSF at opc_prud_risk@cssf.lu
Suggested considerations
Review the CSSF consultation paper “Guidance on Money Market Fund Weekly Liquid Asset Levels” in detail and map the proposed WLA resilience benchmarks against existing MMF liquidity policies, procedures and internal limits.
Perform a quantitative impact analysis comparing each MMF’s historical and current WLA levels against both MMFR minimum requirements and the Commission’s market resilience benchmarks (20% for VNAV; 40% for LVNAV and CNAV) to identify potential shortfalls or pressure points.
Assess and, where necessary, update MMF liquidity risk management frameworks to incorporate explicit internal WLA targets, triggers and escalation procedures linked to the new resilience benchmarks, including governance oversight and board reporting.
Integrate the proposed WLA resilience levels into stress testing programmes under Article 28 MMFR, ensuring scenarios reflect the ability of funds to maintain or restore WLA around the benchmark levels under severe but plausible market stress.
Revisit know‑your‑investor / liability profile analysis under Article 27 MMFR to ensure that internal WLA targets adequately reflect investor concentration, redemption behaviour, dealing frequency and distribution channels.
What changed
- The CSSF, in coordination with the European Commission, AMF (France) and Central Bank of Ireland, is consulting on national guidance that operationalises the Commission’s “market resilience” levels...
The guidance will introduce non-binding but supervisory‑relevant WLA benchmarks designed to indicate when an MMF’s liquidity profile may warrant closer scrutiny and additional supervisory engagement.
The consultation builds on the European Commission’s 11 May 2026 report, which identifies WLA benchmarks of 20% for VNAV MMFs and 40% for LVNAV and CNAV MMFs, compared with the MMFR regulatory minima...
The guidance is intended to support more consistent and well‑calibrated supervision of MMFs across the EU, specifically on liquidity resilience under stress.
MMFs that fall below the identified “market resilience” WLA levels, even while remaining compliant with the MMFR minimum percentages, can expect increased supervisory scrutiny, closer monitoring and...
Compliance impact
The immediate legal impact is limited because the text is a consultation on guidance, not a binding rule change, but the direction of travel is towards higher de‑facto liquidity expectations and more intrusive supervision where WLA levels fall below resilience benchmarks. Non‑alignment with the eventual guidance is likely to result in increased supervisory challenge, potential remediation demands and heightened risk that liquidity weaknesses are escalated within the CSSF’s prudential risk framework.
The CSSF has launched a consultation on new **Guidance on Money Market Fund (MMF) Weekly Liquid Asset Levels**, signalling its intention to clarify supervisory expectations on the calibration and use of weekly liquid asset (WLA) buffers under the EU Money Market Funds Regulation (MMFR). This matters for compliance teams because it will likely drive changes to MMF liquidity risk frameworks, escalation triggers, governance around liquidity thresholds, and potentially the design of internal stress tests and contingency plans.
---
Key dates
TBD (final guidance – est. late 2026)
– Expected date for CSSF to publish final guidance on MMF weekly liquid asset levels, following review of consultation feedback
08 June 2026
– CSSF publishes consultation communiqué “Guidance on Money Market Fund Weekly Liquid Asset Levels” and opens consultation on its proposed guidance
– Expected closing date for industry comments on the consultation (to be confirmed once the full consultation paper and response deadline are made available by CSSF)
Suggested considerations
Review the CSSF consultation paper in full as soon as it is available and identify all proposed expectations relating to weekly liquid asset levels, monitoring, and escalation.
Map the proposed CSSF guidance against current MMF liquidity policies, prospectus disclosures, and internal procedures to identify gaps and potential areas needing enhancement.
Assess whether existing MMF weekly liquidity monitoring tools, dashboards, and reporting are sufficient to meet anticipated CSSF expectations on frequency, granularity, and early warning indicators.
Evaluate the current escalation framework for declining WLA levels, including board and senior management involvement, and update governance documentation to align with the likely CSSF approach to thresholds and decision‑making.
Review MMF stress‑testing methodologies to ensure that scenarios adequately capture severe but plausible redemption and market stress in relation to WLA levels and that results are integrated into risk appetite and contingency planning.
What changed
Given the consultation nature and the absence of a published consultation text in the extract, the following points reflect what compliance teams should reasonably anticipate and prepare for, based...
The CSSF is consulting on formal guidance that will specify how MMFs domiciled in Luxembourg should determine, monitor, and maintain weekly liquid asset levels under the EU Money Market Funds...
The guidance is expected to operationalise the MMFR WLA requirements (for example, minimum weekly liquidity levels and interaction with redemption activity) by setting out supervisory expectations on...
The consultation will likely address the interaction between WLA levels and the use of liquidity management tools (such as gates, fees, or suspensions), including expectations on when and how...
The CSSF is expected to clarify how MMFs should incorporate WLA targets and thresholds into their internal risk management policies, including stress-testing assumptions, early warning indicators,...
Compliance impact
Non‑compliance with the forthcoming CSSF guidance, once finalised, could result in supervisory findings, remediation programmes, and potential restrictions on MMF activities, particularly in stressed markets where liquidity management failures are highly scrutinised. Given MMFs’ systemic importance, firms should treat this as a high‑impact development for liquidity risk management, board oversight, and investor protection.
IOSCO's final report on CIS valuation practices is an informational update consolidating valuation principles for collective investment schemes and hedge funds. It addresses disclosure and valuation standards across fund types, particularly relevant for asset managers and hedge funds managing less liquid and private...
ESMA Guidelines on stress test scenarios under Article 28 of the Money Market Fund Regulation – Update 2025 (ESMA50-481369926-30585)
AI Analysis
Circular CSSF 26/911 informs Luxembourg money market fund (MMF) managers that the CSSF is integrating ESMA’s 2025 update of the stress test scenarios under Article 28 of the Money Market Fund Regulation (MMFR), and that these new ESMA Guidelines now form part of the Luxembourg supervisory expectations. The circular repeals and replaces Circular CSSF 25/877 as of 26 May 2026 and requires MMFs and their managers to apply the 2025 stress test parameters for MMF reporting from the reporting date 30 June 2026 onwards, driving immediate model, data, and reporting changes.
Key dates
26 March 2026
- ESMA publishes the English, French, and German translations of the 2025 Guidelines on stress test scenarios under Article 28 MMFR on its website, starting the two‑month period to application
26 May 2026
- Circular CSSF 26/911 enters into force and Circular CSSF 25/877 is repealed and replaced, making the 2025 ESMA Guidelines the applicable stress testing framework in Luxembourg
30 June 2026 Deadline
- MMFs and MMF managers must apply the 2025 ESMA Guidelines for the preparation of the required MMF reporting as from the reporting date 30 June 2026 onwards, meaning that stress test calculations underlying this and subsequent reports must be based on the 2025 parameters
Suggested considerations
Identify all MMFs and MMF mandates in scope of Regulation (EU) 2017/1131 for which the CSSF is the competent authority and confirm that they are currently using the 2024 ESMA stress test framework under Circular CSSF 25/877.
Obtain and review in detail the ESMA 2025 Guidelines on stress test scenarios (ESMA50-481369926-30585) and the annexed parameters as integrated by Circular CSSF 26/911, comparing them line‑by‑line to the 2024 version to map all methodological and parameter changes.
Update the MMF stress testing policy and procedures to reference Circular CSSF 26/911 and the 2025 ESMA Guidelines, including explicit descriptions of the scenarios, calibration choices, modelling techniques, and governance for scenario approval.
Recalibrate stress testing models and tools used for MMFs to reflect the 2025 common reference parameters, ensuring that interest rate shocks, credit spread moves, liquidity shocks, redemption scenarios, and concentration risks are aligned with the new ESMA specifications.
Perform impact analyses on representative MMFs using both 2024 and 2025 parameters to quantify changes in stress outcomes, and prepare internal briefing materials for senior management and boards explaining the impacts on liquidity and risk profiles.
What changed

The circular reiterates that MMFs and their managers must tailor the ESMA reference scenarios to the specificities of each MMF, adding additional risk factors or requirements where needed to ensure...
Compliance impact
Non‑compliance with Circular CSSF 26/911 and the integrated 2025 ESMA stress test Guidelines can lead to MMF reporting deficiencies, supervisory findings, and potential risk‑management remediation measures imposed by the CSSF, including expectations to strengthen liquidity and governance. Persistent or material breaches could contribute to more intrusive supervisory engagement, restrictions on MMF activities, or sanctions under the MMFR and Luxembourg supervisory framework.

ESMA Guidelines on Liquidity Management Tools (LMTs) of UCITS and open-ended AIFs (ESMA34-671404336-1364)
AI Analysis
Circular CSSF 26/910 announces the CSSF's application of ESMA Guidelines on Liquidity Management Tools (LMTs) for UCITS and open-ended AIFs, establishing standards for selecting, calibrating, and using LMTs to manage liquidity risks and mitigate financial stability threats. This matters for Luxembourg investment fund managers (IFMs) as it enforces uniform EU-wide supervisory practices under UCITS Directive Article 18a(2) and AIFMD Articles 16(2b)/(2c), holding IFMs primarily accountable for liquidity risk oversight.
Key dates
15 April 2026
Publication and CSSF application date of ESMA Guidelines via Circular CSSF 26/910
Suggested considerations
Review and Update Policies: IFMs must select, calibrate, activate/deactivate LMTs per ESMA guidelines, documenting fair/reasonable ADT calibration (e.g., transaction costs, market impact analysis).
Demonstrate Compliance: Be prepared to show regulators liquidity risk management, including at least one quantitative LMT, one ADT, and condition-specific tools; integrate with UCITS/AIFMD requirements.
Risk Management Integration: Ensure primary responsibility for LMTs, with consistent supervisory application; open-ended SIFs to cross-reference with (EU) 2026/465.
Supervisory Preparedness: Maintain records of previous transactions for market impact estimation and overall LMT rationale.
What changed
- Adoption of ESMA Guidelines: CSSF formally applies ESMA's guidelines (ESMA34-671404336-1364), focusing on LMT selection (e.g., redemption gates, suspension of redemptions/dealings, side pockets),...
Calibration Requirements: IFMs must demonstrate fair and reasonable ADT calibration for normal and stressed conditions, including explicit transaction costs and, where appropriate, estimated implicit...
LMT Recommendations: IFMs should select at least one quantitative-based LMT, one ADT, one for normal conditions, and one for stressed conditions; consider additional measures.
Scope Expansion Recommendation: Open-ended SIFs (not under Part II of the 2010 Law) should consider the circular alongside Commission Delegated Regulation (EU) 2026/465.
Compliance impact
Urgency: High – Published today (15 April 2026), this imposes immediate supervisory expectations on liquidity risk management for Luxembourg's dominant fund sector, where non-compliance risks enforcement under UCITS/AIFMD. IFMs must promptly review LMT frameworks to avoid supervisory scrutiny, especially amid potential market stress.

Survey on the amount of covered deposits held on 31 March 2026
AI Analysis
Circular CSSF-CPDI 26/50 mandates a recurring annual survey on the amount of **covered deposits** held as of **31 March 2026** by specified Luxembourg credit institutions, to support the Fonds de garantie des dépôts Luxembourg (FGDL) in meeting Deposit Guarantee Scheme (DGS) requirements under the 2015 Law and DGSD. This matters for compliance as it ensures institutions contribute accurately to the FGDL's buffer (targeting 2% of covered deposits by 2026), with data also feeding into Single Resolution Board (SRB) calculations for resolution funding.
Key dates
31 March 2026
- Reference date for snapshot of covered deposits
30 April 2026 Deadline
(inferred from pattern in prior circulars like 25/49) - Likely submission deadline for survey data to CPDI (exact date in full PDF; aligns with one-month post-reference in predecessors)
Suggested considerations
Compile data on covered deposits (eligible deposits up to €100,000 per depositor, per Article 163 of 2015 Law), excluding items per Article 172 (e.g., financial institutions, life insurance).
Report detailed breakdowns: total eligible/covered deposits, omnibus/fiduciary accounts (with beneficiary counts), natural vs. legal persons, branch-level data.
Submit via specified format (per attached specs, unchanged from priors) to CPDI by deadline; quarterly data ongoing per CSSF-CPDI 17/07.
Ensure alignment with FGDL contributions under CSSF-CPDI 25/48.
What changed
This circular introduces no substantive changes to survey content, methodology, or reporting specifications compared to prior issuances (e.g., CSSF-CPDI 25/49 for 31 December 2025). Updates are limited to the reference date (31 March 2026) and associated deadlines, maintaining the risk-based ex-ante contribution method from Circular CSSF-CPDI 20/21 and quarterly reporting under CSSF-CPDI 17/07.
Compliance impact
Urgency: High – Immediate action required today (publication date) to prepare for 31 March 2026 snapshot (just 5 days away), with submission likely due early May 2026. Non-compliance risks FGDL penalties, inaccurate contributions (impacting 0.8% extra buffer to 2% DGSD minimum), and SRB reporting failures under Regulation (EU) 2015/63; recurring nature demands robust quarterly data processes.
Amendment of Circular CSSF 18/703 on the introduction of a semi-annual reporting of borrower related residential real estate indicators
AI Analysis
Circular CSSF 26/908 amends Circular CSSF 18/703 to update semi-annual reporting requirements for borrower-related residential real estate indicators, enhancing supervisory oversight of credit risk in Luxembourg's financial sector. Published today (25 March 2026), it matters for credit institutions as it refines data collection to better monitor real estate lending exposures amid potential market vulnerabilities.
Key dates
17 December 2018
- Original issuance of Circular CSSF 18/703 introducing semi-annual reporting
25 March 2026
- Publication date of Circular CSSF 26/908 (today)
Suggested considerations
Download and review the full Circular CSSF 26/908 (291.96Kb PDF) and the updated consolidated Circular CSSF 18/703 (258.91Kb PDF) from the CSSF website: https://www.cssf.lu/en/Document/circular-cssf-26-908/.
Conduct a gap analysis of current reporting processes against the amended requirements for borrower-related residential real estate indicators.
Update internal systems, data collection templates, and reporting workflows to ensure accurate semi-annual submissions to the CSSF.
Train relevant compliance, risk, and finance teams on changes; document compliance confirmations for audit trails.
What changed
The circular introduces amendments to the original Circular CSSF 18/703 (itself amended by Circulars CSSF 20/737 and 21/772), focusing on semi-annual reporting of indicators tied to borrowers in residential real estate. Specific changes are not detailed in the provided summary or full content excerpt, but they likely involve refinements to reporting templates, data granularity, or submission processes to align with evolving EU prudential standards on real estate risk monitoring. The updated consolidated version of Circular CSSF 18/703 is now available as a 258.91Kb PDF.
Compliance impact
Urgency: Medium - This is a targeted amendment to existing reporting obligations rather than a new regime, reducing immediate disruption, but non-compliance risks supervisory scrutiny, fines, or enhanced monitoring given CSSF's focus on real estate risk. It matters for maintaining accurate credit risk data, especially in a potentially volatile residential property market, supporting broader prudential stability.
The CSSF Technical FAQ on Regulation No 20-08 provides implementation guidance on **loan-to-value (LTV) limits for residential real estate credit in Luxembourg**, establishing borrower-based macroprudential measures designed to limit leverage in the mortgage market. This guidance is critical for lenders operating in Luxembourg as it clarifies how to calculate own funds, determine LTV compliance, and apply temporary portfolio exemptions that have been extended through June 30, 2025.
Key dates
December 3, 2020
- CSSF Regulation No 20-08 originally published
January 1, 2021

- Most recent Technical FAQ version published (prior to March 9, 2026 update)
Suggested considerations
*For all lenders:
*Verify LTV compliance calculations for all new residential mortgage originations using the framework specified in the FAQ, ensuring own funds are calculated as actual equity contributions from borrowers
*Implement dual LTV tracking for borrowers financing new property through sale of existing property, ensuring compliance with both interim and final LTV ratios
*Document own funds sources carefully, particularly when cash collateral or sale proceeds are used, as these are only permitted for loans with initial LTV below 100%
*Prepare for June 30, 2025 transition by:

on the introduction of a semi-annual reporting of borrower-related residential real estate indicators
AI Analysis
Circular CSSF 18/703 introduces semi-annual reporting requirements for Luxembourg-based lenders on borrower-related residential real estate (RRE) indicators to monitor macroprudential risks in the RRE lending market, in line with ESRB Recommendation 2016/14 (as amended). It matters for compliance because it mandates data collection via a dedicated CSSF template, with exclusions only for banks below EUR 10 million in outstanding RRE exposures, ensuring supervisory oversight of lending standards. The circular has been iteratively amended (CSSF 20/737, 21/772, 26/908), with the latest update on 25 March 2026 refining reporting processes.
Key dates
17 Dec 2018
Original Circular CSSF 18/703 published; reporting obligation introduced
19 Feb 2020
Circular CSSF 20/737 and FAQ published; clarified exemptions and scope
10 May 2021
Circular CSSF 21/772 amendment published

Circular CSSF 26/908 amendment published (today's date); immediate implementation expected for upcoming cycles
Ongoing (semi Deadline
annual); Reports due in April (ref. 31 Dec) and October (ref. 30 Jun) each year
Suggested considerations
Download and use the dedicated RRE data template from the CSSF website (https://www.cssf.lu/en/Document/circular-cssf-18-703/).
Assess total outstanding RRE exposure; if > EUR 10 million, collect data on new/outstanding exposures per reference dates (30 Jun/31 Dec).
Ensure IT systems store/process RRE indicators (e.g., borrower debt metrics, collateral details) for semi-annual extraction.
Submit reports to CSSF in April/October; review amendments (20/737, 21/772, 26/908) and FAQ for updates.
For exempt banks: Confirm eligibility annually; no zero report required.
What changed

Compliance impact
Urgency: High – Ongoing semi-annual obligation with latest amendment today (25 Mar 2026, CSSF 26/908) likely affects the next October 2026 cycle (ref. 30 Jun 2026); non-compliance risks supervisory sanctions, as it supports macroprudential monitoring under ESRB framework. Firms must validate systems/data immediately post-amendment to avoid gaps in reporting population.

This publication is a CSSF FAQ in relation to the use by Luxembourg-domiciled UCITS of the following Securities Financing Transactions: securities lending transactions, reverse repurchase agreement transactions and repurchase agreement transactions. The objective of the FAQ is to bring further clarity concerning the…
AI Analysis
This CSSF FAQ (Version 2) provides guidance on the use of securities financing transactions (SFTs)—specifically securities lending, reverse repurchase agreements, and repurchase agreements—by Luxembourg-domiciled UCITS, clarifying regulatory requirements based on the applicable framework and CSSF's supervisory experience. It matters because it updates prior guidance to reflect evolved practices, helping UCITS managers ensure compliant SFT usage amid heightened scrutiny on liquidity, risk management, and investor protection in Luxembourg's fund sector.
Key dates
18 December 2020
Original publication date of Version 1
12 February 2026
Update date for Version 2; (effective immediately as non-binding guidance)
Suggested considerations
Review and update policies: UCITS managers must assess current SFT programs against the FAQ's clarifications, ensuring alignment with regulatory framework (e.g., UCITS Directive) and CSSF supervisory expectations on risk, collateral, and transparency.
Enhance disclosures: Update fund prospectuses, KIIDs, and annual reports to reflect SFT usage, risks, and revenues, per CSSF emphasis on investor clarity.
Conduct gap analysis: Audit SFT counterparties, collateral management, and liquidity tools for compliance; remediate any deviations based on gained supervisory experience.
Train staff and delegates: Implement training on updated FAQ to cover securities lending, repos, and reverse repos specifics.
Monitor ongoing use: Maintain records of SFT volumes, counterparties, and performance for CSSF inspections; integrate with broader UCI regulatory updates like risk-spreading.
What changed
The document is an updated FAQ (Version 2), originally published on 18 December 2020 and revised on 12 February 2026, but the provided content does not detail specific changes from Version 1 beyond incorporating recent supervisory experience and regulatory framework updates. It emphasizes clarity on SFT eligibility, operational controls, and risk mitigation for UCITS, without introducing new prohibitions or mandates visible in the summary; full details require accessing the PDF (201.4Kb).
Compliance impact
Urgency: High – The 12 February 2026 update coincides with today's date, signaling immediate relevance for Luxembourg UCITS engaging in SFTs, which are common for yield enhancement but carry liquidity and counterparty risks. Non-compliance risks supervisory actions, given CSSF's focus on practical experience; firms should prioritize review to avoid findings in upcoming audits or inspections, especially amid parallel 2026 updates on UCI investments.

The Commission de Surveillance du Secteur Financier (CSSF) has updated its FAQ on crypto-asset investments by undertakings for collective investment, effective February 4, 2026, to align with the EU's Markets in Crypto-Assets Regulation (MiCAR). This update establishes clear investment limits and licensing requirements for UCITS and AIFs investing in crypto-assets, fundamentally reshaping how Luxembourg-regulated funds can structure crypto exposure.
Key dates
4 February 2026 Deadline
- FAQ Version 7 effective date; MiCAR compliance requirements become operative
1 July 2026 Deadline
- Deadline for Virtual Asset Service Providers (VASPs) to transition from registration to authorization under MiCAR or cease operations
Suggested considerations
*For UCITS Managers:
by-case assessment of crypto-asset investment impact on fund risk profiles
specific risks (volatility, liquidity, technological risk)
asset investments
*For AIFMs Managing AIFs with Crypto Exposure:
What changed
The regulatory framework introduces several material modifications:
Investment Exposure Limits
UCITS may invest indirectly in crypto-assets for a maximum of 10% of their net asset value (NAV). These indirect investments are restricted to transferable securities that do not embed derivatives. AIFs open to retail investors other than well-informed investors face the same 10% NAV ceiling.
MiCAR Alignment
The FAQ modifications directly reflect the entry into force of Regulation (EU) 2023/1114 on markets in crypto-assets.
The CSSF has released Version 7 of its FAQ on Crypto-Assets for Undertakings for Collective Investment, updated on February 4, 2026, to reflect the entry into force of the Markets in Crypto-Assets Regulation (MiCAR). This guidance establishes binding investment limits, authorization requirements, and risk management standards for UCITS and AIFs investing in crypto-assets, fundamentally reshaping how Luxembourg-regulated collective investment schemes can engage with digital assets.
Key dates
February 4, 2026
- FAQ Version 7 effective date (entry into force of MiCAR alignment)
July 1, 2026 Deadline
- Deadline for Virtual Asset Service Providers (VASPs) to transition to CASP authorization or cease operations
No specific implementation grace period
- The FAQ does not specify a transition period for existing funds exceeding the 10% limit; firms should clarify this with the CSSF immediately
Suggested considerations
*Immediate Compliance Steps:
*Portfolio Audit: Conduct a comprehensive review of all UCITS and AIF holdings to identify current and potential crypto-asset exposures, both direct and indirect (including derivatives with crypto underlyings).
*Investment Policy Updates: Revise fund documentation, prospectuses, and investment policies to reflect the 10% NAV limits and MiCAR compliance requirements.
*Risk Management Assessment: Update risk management policies to address crypto-asset volatility, liquidity, and technological risks, with case-by-case impact assessments on fund risk profiles.
*Investor Notification: Ensure transparent and timely communication with investors regarding any crypto-asset investments or policy changes.
What changed
The most significant regulatory modifications in Version 7 include:
Investment Limits for UCITS
UCITS may invest indirectly in crypto-assets for a maximum of 10% of their net asset value (NAV). These indirect investments are limited to transferable securities that do not embed derivatives in accordance with Article 10 of the Grand-ducal Regulation of 8.
Investment Limits for AIFs
AIFs open to retail investors other than well-informed investors may invest in crypto-assets for a maximum of 10% of their NAV.

Application of the Guidelines of the European Banking Authority on the management of environmental, social and governance (ESG) risks (EBA/GL/2025/01)
AI Analysis
Circular CSSF 26/905 mandates the application of EBA Guidelines (EBA/GL/2025/01) on managing **ESG risks** for Luxembourg-supervised institutions, requiring integration of environmental, social, and governance risk identification, measurement, management, and monitoring into internal processes. This aligns with CRD amendments (Articles 74, 76, 87a) and emphasizes proportionality to institutions' business models, with plans including timelines, targets, and milestones toward EU climate goals like net-zero by 2050. It matters for compliance as it embeds ESG into prudential supervision, potentially impacting capital, risk frameworks, and supervisory reviews.
Key dates
20 January 2026
- Circular published by CSSF
1 April 2026
- Application date for Less Significant Institutions (other than SNCIs)
11 January 2027
- Application date for SNCIs (dependent on CRD transposition)
Suggested considerations
Map and integrate ESG risks into governance, risk management frameworks, and business strategies, proportionate to scale/risk exposure.
Develop and document ESG risk management plans with quantifiable targets, milestones, timelines, and scenario analyses (broad requirements now; detailed later).
Conduct assessments of ESG risks in portfolios, including sustainability products, transition finance, and loan origination policies, for SREP submission.
Embed in internal processes per Articles 74, 76, 87a CRD: identify/measure ESG risks (minimum standards), monitor over time horizons, and report to CSSF.
Review and update existing policies/systems for compliance by applicable dates; prepare for CSSF supervisory evaluation of plan robustness.
What changed
- Institutions must establish proportionate strategies, policies, processes, and systems for ESG risk management, covering short-, medium-, and long-term horizons, including transition and physical...
Develop plans per Article 76(2) CRD with specific timelines, intermediate quantifiable targets, and milestones to address ESG financial risks, consistent with EU objectives (e.g., 55% GHG reduction...
Incorporate ESG into internal governance, risk appetite, and supervisory review processes (SREP), with scenario analysis requirements (to be detailed in future EBA guidelines).
Applies minimum standards and methodologies for ESG risk identification, measurement, monitoring, and impact assessment on institutions' exposures.
No requirement for full alignment with specific sustainability trajectories, but plans must consider transition risks and institutions' ESG product offerings, loan policies, and targets.
Compliance impact
Urgency: High - With application starting 1 April 2026 (just over 2 months from publication), firms face immediate pressure to gap-analyze current ESG frameworks against EBA standards, especially for SREP integration and long-term risk planning. Non-compliance risks supervisory scrutiny, capital add-ons, or enforcement, as ESG is now a core prudential pillar amid EU sustainability push; smaller institutions get a head-start but must act swiftly given proportionality demands.
This regulatory update on resolution reporting requirements is relevant for banking, investment management, and wealth management firms. It covers prudential and capital requirements, reporting and disclosure obligations, as well as operational resilience considerations.

Survey on the amount of covered deposits held on 31 December 2025
AI Analysis
Circular CSSF-CPDI 25/49 is a **mandatory quarterly reporting requirement** for Luxembourg credit institutions and postal financial service providers to submit data on covered deposits as of December 31, 2025. This survey directly feeds into the Single Resolution Fund's annual target level calculation and the Luxembourg deposit guarantee scheme's contribution assessments, making it essential for regulatory compliance and fund management.
Key dates
December 24, 2025
- Circular publication date
December 31, 2025
- Reference date for the survey
January 30, 2026 Deadline
- Deadline for transmitting average covered deposits data to the Single Resolution Board
Suggested considerations
*Calculate covered deposits as defined in Article 163 of the 2015 law, including balance and accrued interest (even if not yet due)
*Report eligible deposits after applying exclusions under Article 172 of the 2015 law, including exclusions for financial institutions and life insurance products

What changed
The circular explicitly states that no substantive changes have been made to the survey process compared to previous quarters. The only modifications are administrative: the reference date (December 31, 2025) and the submission deadline (January 30, 2026). The specifications for data collection, definitions of covered and eligible deposits, and reporting methodologies remain unchanged from prior circulars, particularly Circular CSSF-CPDI 16/02 as amended by Circular CSSF-CPDI 23/35.
Repeal of Circular CSSF 19/731 regarding the documents to be submitted on an annual basis by credit institutions.
AI Analysis

This matters because it streamlines compliance by centralizing and updating requirements online, reducing reliance on static circulars while maintaining submission obligations. Credit institutions must transition to the new process to avoid disruptions in prudential reporting.
Key dates
12 December 2019
- Original issuance of repealed Circular CSSF 19/731 (archived on 23 December 2025)
23 December 2025
- Publication and effective date of Circular CSSF 25/902, repealing Circular CSSF 19/731; transition to website-based list begins
Suggested considerations
Review the CSSF Prudential reporting webpage (https://www.cssf.lu/en/prudential-reporting-credit-institutions/) and summary table (https://www.cssf.lu/en/Document/summary-of-documents-to-be-submitted-on-an-annual-basis/) to identify current document lists, categories, channels, and deadlines.
Update internal reporting processes, templates, and workflows to reference the website instead of the repealed circular.
Confirm ongoing annual submissions via specified electronic channels; test interactive table for applicability to the institution's profile.
Archive references to Circular CSSF 19/731 in policies and train staff on the change.
What changed
- Repeal of prior circulars: Circular CSSF 19/731 and its amendment via Circular CSSF 19/710 are fully repealed, eliminating the fixed list of annual submission documents.
Shift to website-based guidance: The updated list of required documents, affected entity categories, electronic submission channels, and deadlines is now published on the CSSF’s Prudential reporting...
Ongoing obligations: The requirement to submit documents annually remains unchanged; only the reference source and potential content updates via the website are modified.
Compliance impact
Urgency: Medium – The repeal does not alter core submission obligations but requires procedural updates to avoid non-compliance with potentially evolving lists under CRR3 alignments. It matters for operational efficiency, as failure to adapt could lead to missed deadlines or incorrect submissions, especially with website updates tied to EU regulations like Regulation (EU) 2024/1623 (CRR3, applicable from 1 January 2025). Institutions should prioritize review before the next annual cycle to ensure seamless reporting.

This regulatory update relates to the profit and loss account of credit institutions, which is relevant for banking and investment management firms. The topics of prudential/capital requirements and reporting/disclosure are also applicable. The update is informational in nature, so the urgency is low.
relating to specialised investment funds, investment companies in risk capital and undertakings for collective investment subject to Part II of the Law of 17 December 2010
AI Analysis
Circular CSSF 25/901 consolidates and modernizes the supervisory framework for Luxembourg specialised investment funds (SIFs), investment companies in risk capital (SICARs), and undertakings for collective investment subject to Part II of the Law of 17 December 2010 (Part II UCIs), including their sub-funds. It streamlines investment rules, diversification limits, borrowing, disclosures, and risk management while enhancing flexibility for sophisticated investors and formalizing prior informal guidance, reducing regulatory complexity without compromising investor protection.
Suggested considerations
Review and update fund documents (e.g., sales documents, instruments of incorporation) to include mandated disclosures on investment strategy/limits, risks, UCIs/vehicles, borrowing, liquidity tools, and retail-specific warnings.
Assess and document compliance with new/relaxed diversification, borrowing, and SICAR investment rules; apply for CSSF derogations where justified.
Ensure risk-spreading in derivatives/collateral and deployment of SICAR cash into eligible assets; confirm look-through for intermediaries.
For retail-marketed funds: Limit investments/UCIs to 25%, cap borrowing at 70%, add prominent risk warnings for illiquids/long-duration.
Maintain robust governance/documentation to leverage flexibility; reference CSSF's Compilation for concepts.
What changed
- Diversification and investment limits: Introduces tailored percentage-based thresholds; for funds marketed to unsophisticated retail investors, limits remain at 25% per issuer/UCI/asset, raised to...
SICAR-specific rules: Confirms risk capital investments (e.g., equity, mezzanine) must align with development objectives, exceed mere market risk, and deploy incoming cash into eligible assets;...
Borrowing: For retail-exposed SIFs/Part II UCIs, investment borrowing capped at 70% of assets/commitments; no hard cap for sophisticated investor funds if disclosed, with SICARs limited to risk...
Derivatives and techniques: Permits use if economically appropriate (e.g., risk/cost reduction), with risk-spreading via diversified underlyings/collateral; counterparty risk limited if...
Urgency: High – Formalizes prior informal guidance into binding rules with enhanced flexibility but stricter retail protections and disclosure mandates, requiring immediate document reviews/updates for non-compliant SIFs/SICARs/Part II UCIs to avoid supervisory scrutiny or authorization issues; critical for funds targeting private markets or retail.
Revision and remodelling of the rules to which Luxembourg undertakings governed by the Law of 30 March 1988 on undertakings for collective investment (“UCI”) are subject
AI Analysis
Circular IML 91/75, as amended up to CSSF Circular 25/901, consolidates and modernizes the supervisory framework for Luxembourg Part II UCIs, SIFs, and SICARs, refining rules on diversification, borrowing, risk-spreading, and disclosures while tailoring requirements to investor profiles. It matters because it streamlines fragmented regulations, enhances fund competitiveness, and formalizes CSSF expectations without mandating immediate changes for pre-existing funds, reducing compliance burdens while promoting transparency and flexibility. This update aligns administrative practices with market realities, repealing outdated circulars to eliminate ambiguity.
Suggested considerations
Review and update offering documents/prospectuses for enhanced transparency on risks, limits, borrowing, liquidity tools (e.g., gates, notice periods), redemption processes, and investor-specific warnings.
Align fund documentation/terminology with CSSF Compilation of key concepts for consistency in filings and communications.
Disclose ramp-up/wind-down periods, potential derogations, and life extensions clearly; seek CSSF approval for exemptions where justified.
For SICARs: Ensure risk capital investments meet modernized criteria; apply look-through for limits.
Assess portfolio compliance for new funds/compartments; leverage flexibility for sophisticated investors but maintain robust governance.
What changed
- Consolidation and Repeals: Repeals CSSF Circulars 02/80, 07/309, 06/241, and Chapters G and I of IML 91/75; renders CSSF 08/356 and Chapter H of IML 91/75 inapplicable to Part II UCIs.
Flexible Diversification Rules: Introduces investor-category-based thresholds (e.g., stricter for retail, looser for sophisticated investors); allows CSSF derogations for SIFs/Part II UCIs with...
Borrowing Limits: New limits for SIFs/Part II UCIs (e.g., 70% of net assets, excluding temporary borrowings tied to commitments); tailored by investor type.
Enhanced Disclosures: Offering documents must detail investment policies, risks (especially private equity for retail), subscription/redemption processes, liquidity tools, gates, and amendment...
SICAR Risk Capital: Modernizes definition to include equity, loans, bonds, mezzanine; clarifies direct/indirect investments with three cumulative elements (risk of total loss, no redemption rights,...
Compliance impact
Urgency: Medium – Not critical as existing funds are grandfathered with no retroactive changes required, but high relevance for new launches or material updates post-19 Dec 2025. It matters for operational efficiency (streamlined rules reduce fragmentation) and investor protection (tailored risks/disclosures), potentially lowering long-term costs while mitigating supervisory scrutiny; failure to update docs could delay approvals or trigger CSSF queries.
Rules applicable to undertakings for collective investment when they employ certain techniques and instruments relating to transferable securities and money market instruments
AI Analysis
Circular CSSF 08/356, as amended by Circular CSSF 25/901, establishes detailed rules for Luxembourg undertakings for collective investment (UCIs), including UCITS and alternative investment funds (AIFs), on the use of techniques and instruments relating to transferable securities and money market instruments, such as securities lending, repo transactions, and over-the-counter (OTC) derivatives. It matters because it ensures investor protection, risk management, and market stability by imposing strict eligibility, collateral, and operational requirements, aligning Luxembourg funds with EU standards under UCITS and AIFMD directives. Compliance is critical for Luxembourg-domiciled funds engaging in these activities to avoid regulatory sanctions and operational disruptions.
Key dates
23 December 2008
- Original Circular CSSF 08/356 effective date for UCITS III implementation
21 July 2011
- Partial updates for UCITS IV alignment
22 July 2013
- Extension to AIFs under AIFMD transposition
15 October 2025
- Issuance of amending Circular CSSF 25/901
01 January 2026
- Effective date for amendments (e.g., new collateral rules, reporting formats)
Suggested considerations
*Policy Review & Update: Revise fund prospectuses, KIIDs, and risk management policies to reflect amended limits (e.g., counterparty caps, ESG collateral) within 3 months of 01 January 2026.
*Risk Management Systems: Implement or upgrade systems for daily collateral valuation, stress testing, and exposure monitoring; conduct gap analysis against Section 4 requirements.
*Counterparty Due Diligence: Reassess OTC counterparties for eligibility (e.g., EMIR clearing thresholds); negotiate ISDA/CSA agreements with updated haircuts.
*Operational Setup: Appoint triparty agents where required; ensure collateral segregation complies with Section 5.
*Reporting & Disclosure: Prepare for new quarterly CSSF filings (template in Annex 1); disclose revenues/reinvestments from techniques in annual reports (Article 14 UCITS Law).
What changed
The original Circular CSSF 08/356 (2008) transposed UCITS III requirements on eligible techniques like securities lending and repos.
Expanded collateral rules: Collateral must now include sustainable assets meeting SFDR criteria, with daily marking-to-market and haircuts adjusted for liquidity and credit risk (Section 3).
Counterparty exposure limits: Net exposure to a single OTC counterparty capped at 10% of net asset value (NAV), down from previous thresholds in some cases, with mandatory collateralization (Section...
Operational safeguards: Mandatory use of triparty agents for repos, enhanced segregation of collateral, and annual stress testing disclosures (Section 5, as amended).
Reporting enhancements: Quarterly reports to CSSF on transaction volumes, risks, and revenues from these activities (Annex 1, updated).
These align with ESMA guidelines (e.g., ESMA/2012/832 on OTC...
Compliance impact
Urgency: High - Immediate relevance for funds actively using these techniques (common in fixed-income and equity strategies for yield enhancement). Non-compliance risks CSSF fines (up to 5% of NAV), temporary prohibitions on techniques, or fund suspension. With the 01 January 2026 effective date recently passed (as of current context), firms face heightened scrutiny in 2026 reporting cycles; proactive remediation avoids enforcement actions amid CSSF's focus on operational resilience.
Application of the Guidelines of the European Banking Authority on Acquisition, Development, and Construction (ADC) exposures to residential property under Article 126a of Regulation (EU) 575/2013 (EBA/GL/2025/03)
AI Analysis
Circular CSSF 25/899 mandates the application of EBA Guidelines (EBA/GL/2025/03) on Acquisition, Development, and Construction (ADC) exposures to residential property under Article 126a of Regulation (EU) 575/2013 (CRR), specifying conditions for reducing the risk weight from 150% to 100% on qualifying exposures. This matters for Luxembourg credit institutions as it directly impacts capital requirements for real estate lending, promoting safer lending practices while aligning with Basel III standards via CRR3 implementation.
Key dates
4 November 2025
- EBA Guidelines (EBA/GL/2025/03) apply across EU (two months post-publication on 27 June 2025 in all official languages)
Review and classify ADC exposures against EBA-defined criteria (e.g., contract thresholds, equity levels, monitoring standards) to determine eligibility for 100% risk weight.
Update internal policies, risk assessment models, and credit approval processes to incorporate "sound lending standards" and EBA specifications, including social housing carve-outs.
Recalculate capital requirements under standardized credit risk approach; report changes via CRR disclosures.
Maintain documentation proving compliance (e.g., deposit proofs, equity valuations) for supervisory audits by CSSF.
Institutions must "make every effort to comply" per EBA Regulation Article 16(3).
What changed
- Introduces precise definitions for CRR Article 126a(2) terms, enabling 100% risk weight (instead of 150%) for ADC exposures to residential property if conditions are met: at least 50% of total...
Mandates "sound standards for lending and credit monitoring" alongside these criteria.
Accounts for social housing/public not-for-profit lending specificities, with tailored rules for regulated entities serving long-term tenant housing.
Replaces prior "particularly high-risk exposure" class with dedicated ADC class under CRR3.
Compliance impact
Urgency: High – Firms with significant ADC portfolios face immediate capital relief opportunities (50bp risk weight reduction) but risk non-compliance penalties if processes aren't updated by early 2026, especially post-CRR3 rollout; misclassification could inflate capital needs amid ongoing Basel implementation.
Fonds de garantie des dépôts Luxembourg (FGDL) – Method for calculating the ex-ante contributions pursuant to Article 182 of the Law of 18 December 2015 on the failure of credit institutions and of certain investment firms
AI Analysis
Circular CSSF-CPDI 25/48, published on 13 November 2025, updates the methodology for calculating ex-ante contributions to the Fonds de garantie des dépôts Luxembourg (FGDL), Luxembourg's deposit guarantee scheme, by aligning risk adjustments with EBA Guidelines and introducing a zero floor for certain calculation components. This matters for Luxembourg credit institutions as it refines risk-sensitive contributions to meet DGSD target levels for two compartments (0.8% and an additional 0.8% of covered deposits), ensuring financial stability while promoting supervisory convergence across the EU.
Suggested considerations
Review and update internal systems/models for contribution calculations to incorporate new risk weights, bounds (Table 2), zero floor for Component 1, and revised formulas in Annexes 1-2.
Validate data reporting for risk indicators (e.g., ROA, LCR, NSFR, NPL) against adjusted sliding scales; ensure alignment with EBA Guidelines for simplicity and resource efficiency.
Prepare for FGDL invoices reflecting compartment-specific rates; monitor covered deposits for surveys (e.g., per Circular 25/49).
Conduct gap analysis against repealed circulars (20/21, 23/34); update policies for mergers, deposit changes, and gap fillings (Γ_λ).
What changed
- Risk Adjustment Updates (Annex 2): Increases weight of 'Return on assets' (ROA) risk indicator from 7.5% to 10%; decreases 'Deposit-size Risk' from 15% to 12.5%; adjusts sliding scale bounds for...
Formula Component Floor (Annex 1): Introduces a zero floor for Component 1 (max(0, A_{j,k})), preventing negative values from offsetting Component 2; retains both components but ensures no...
Contribution Calculation Refinements: Annual contributions per compartment use updated formulas (e.g., formula (1) with max operator); contribution rates are uniform per compartment but...
Repeals Prior Circulars: Repeals CSSF-CPDI 23/34 (4 June 2020) and CSSF-CPDI 20/21 (as amended), replacing the 2020-reviewed method.
Compliance impact
Urgency: High – Institutions must promptly recalibrate risk models ahead of 2026 contributions to avoid miscalculations, penalties, or underfunding risks, as this directly impacts prudential contributions amid ongoing DGSD buildup to 2026; non-alignment with EBA could trigger CSSF scrutiny. Failure to adapt may increase costs for riskier profiles, emphasizing the shift to greater risk sensitivity.

Suggested considerations
Data Reporting: Submit accurate covered deposits data (e.g., as of 31 Dec 2025 per Circular 25/49) and risk indicator metrics (leverage, LCR, NSFR, NPL, etc.) to FGDL/CSSF for ARW calculation; prepare for annual surveys like CPDI 25/45 (31 Mar 2025 snapshot).
Internal Calculations: Model contributions using new formula C_{j,k} = ARW_{j,k} * max(0, max(A_{j,k}) + T_j D_{j-2,k}) * μ; forecast based on historical deposits (D_{j-2,k}) and growth.
Systems Update: Adapt finance/compliance systems for new inputs; align with EBA risk guidelines (https://www.eba.europa.eu/regulation-and-policy/single-rulebook/interactive-single-rulebook/1085).
What changed
- Modified Contribution Formula: Replaces prior methods (e.g., from Circulars CSSF-CPDI 16/01, 17/06, 20/21) with a new structure: Component 1 proportional to covered deposits growth (Γ_{j,k}) at...
Risk Adjustment Introduction: ARW is calculated using a weighted score (minimum 75% on EBA core categories, plus 12.5% deposit-size risk and 10% others) from indicators like leverage ratio (bounds...
Merger/Transfer Handling: For failed/merged institutions, contributions are redistributed proportionally to receiving institutions' deposit increases, capped by their own required amounts; no...
Floor and Alignment: Introduces max(0, A_{j,k}) floor to avoid negative components; ensures EBA compliance, simplicity, and risk sensitivity.
Compliance impact
Urgency: High - Affects 2026 contributions directly, requiring immediate data readiness and modeling by Q1 2026; non-compliance risks penalties, inaccurate payments, or higher costs from poor risk scores. Matters for capital planning as riskier profiles face uplifts, emphasizing proactive risk management amid EU harmonization.
Update of Circular CSSF 22/821 on the Long Form Report, as amended by Circulars CSSF 23/845 and CSSF 24/865
AI Analysis
Circular CSSF 25/897 updates Circular CSSF 22/821 on the Long Form Report (LFR) for credit institutions, further aligning the self-assessment questionnaire (SAQ) with current supervisory priorities such as ML/FT risks and organizational aspects. This matters because it refines reporting to reduce redundancies, enhance transparency in REA assessments, and reflect evolving prudential focuses since prior amendments via Circulars CSSF 23/845 and 24/865, ensuring institutions' reports better support CSSF oversight.
Key dates
31 October 2025
- Issuance date of Circular CSSF 25/897
Three months after financial year Deadline
end; - Annual submission deadline for SAQ to CSSF (unchanged from prior circulars)

Six months after financial year
end; - Aligned submission for REA management letter (per amendments in CSSF 23/845 to Circular 22/826)
Suggested considerations
Complete and submit revised SAQ annually, incorporating new modules on supervisory focuses like ML/FT risks and providing detailed data to REA.
Authorized management: Supply accurate descriptive information to REA for reports, covering client protections, collateral, and AML/CFT procedures across group entities.
REA: Independently assess and report on ML/FT risks and client assets with transparency, quantitative details, and verified management inputs; avoid imprecise language.
Review prior LFR submissions against this update to align with suppressed redundancies and new emphases.
What changed
- Introduces new modules in the revised SAQ to align with supervisory points of focus, building on prior expansions (e.g., credit/counterparty risk, liquidity risk, climate-related risks from CSSF...
Emphasizes REA's independent assessment in the AML/CFT report, requiring exhaustive, transparent evaluations of ML/FT risks across institutions, branches, majority-owned subsidiaries abroad, and tied...
REA must verify and amend descriptive elements provided by management for the Financial Instruments and Funds Report and AML/CFT report, including quantitative metrics like pending file ratios.
Confirms the three-part LFR framework: institution-completed SAQ, REA's client assets protection report (per Article 7 of Grand-ducal Regulation of 30 May 2018), and REA's AML/CFT report; no Agreed...
Enhances REA responsibilities for collateral arrangements and client fund protections under relevant laws.
Compliance impact
Urgency: High - Institutions face immediate refinement needs for 2025 year-end reporting (e.g., SAQ due ~Q1 2026), with stricter REA scrutiny on AML/CFT transparency risking supervisory findings or enforcement if vague assessments persist; aligns with ongoing CSSF push for risk-focused oversight amid regulatory evolution.

Survey on the amount of covered deposits held on 30 September 2025
AI Analysis
Circular CSSF-CPDI 25/47 mandates a regular survey by Luxembourg credit institutions on the amount of covered deposits as of **30 September 2025**, focusing on eligible and covered deposits under the Law of 18 December 2015 on deposit guarantee schemes. It matters because it ensures accurate reporting to the Conseil de protection des déposants et des investisseurs (CPDI) for FGDL (Fonds de garantie des dépôts Luxembourg) compliance, with detailed field-by-field instructions for complex accounts like omnibus and trusts.
Key dates
30 September 2025
- Reference date for snapshot of deposits, eligible deposits, and covered deposits
6 October 2025
- Publication date of the circular by CSSF
Suggested considerations
Collect data on total deposits (field 0100), apply exclusions per Article 172 (field 0201), calculate covered deposits up to €100,000 limit (field 0300), and break down by natural/legal persons, balance thresholds, and special accounts (fields 0210-0330).
For omnibus/trust accounts, obtain and report shares of identifiable entitled persons, apportion by legal status of holder, and ensure fields like 0226 and 0255 reconcile.
Exclude non-creditor accounts or those assimilated to financial institutions/life insurance.
What changed
This circular updates prior guidance (notably CSSF-CPDI 16/02 as amended by CSSF-CPDI 23/35) by specifying the survey reference date of 30 September 2025 and providing granular reporting fields for eligible deposits (e.g., exclusions for financial institution-like structures and life insurance products), covered deposits capped at €100,000 per person, and breakdowns by natural/legal persons, including shares in omnibus accounts, fiduciaries, trusts, sub-accounts, and segregated accounts.
Compliance impact
Urgency: Medium – Past reference date (30 September 2025) as of January 2026 means non-reporting firms risk immediate FGDL non-compliance, fines, or supervisory action from CSSF, but this is a routine quarterly survey (see related Circular CSSF-CPDI 25/49 for December 2025). Matters for prudential reporting accuracy, especially amid EU deposit guarantee harmonization.
This regulatory update relates to the profit and loss account of credit institutions, which is relevant for banking and investment management firms. The topics of prudential/capital requirements and reporting/disclosure are also applicable. The update is informational in nature, so the urgency is low.
Single Resolution Fund – Information request by the Single Resolution Board for the calculation of the 2026 contribution according to Articles 4 and 14 of Commission Delegated Regulation (EU) 2015/63
AI Analysis
Circular CSSF-CODERES 25/21, issued by the CSSF on 29 September 2025, mandates Luxembourg credit institutions to submit specific data via XBRL-formatted Data Reporting Forms (DRFs) to enable the Single Resolution Board (SRB) to calculate 2026 ex-ante contributions to the Single Resolution Fund (SRF) under Articles 4 and 14 of Commission Delegated Regulation (EU) 2015/63. This matters because non-compliance risks SRB using estimates, applying the highest risk multiplier, or penalties, ensuring the financial sector funds resolution costs without taxpayer burden.
Key dates
30 November 2025 Deadline
- SRB decision deadline on whether to calculate/collect 2026 SRF contributions based on DRFs (triggers full additional assurance application)
15 January 2026
- ECB-supervised institutions submit AUP or auditor reports on restatements to CSSF resolution department
16 January 2026, 24:00 CET
- All institutions submit completed DRF in XBRL to CSSF; late/incomplete submissions lead to SRB estimates or highest risk multiplier
Suggested considerations
Download and complete DRF using Annexes (e.g., Annex 3a PDF, Annex 5 User Guide v1.4); submit in XBRL format by deadline.
For ECB-supervised institutions: Provide additional assurances per Annex 7a/7b if SRB proceeds with collections; prepare restatement AUPs with auditor exceptions where applicable.
Align internal systems with CSSF templates early; validate data to avoid SRB assumptions under Article 17(1) DR.
- Introduces data collection for 2026 SRF contributions, conditional on SRB verifying SRF funds fall below 1% of covered deposits in the Banking Union by early 2026.
Mandates XBRL submission of DRFs (except restatements up to 2022 in Excel); provides templates in Annexes 3a, 4, 5 (User Guide), and 7a/7b for additional assurances.
Additional assurance requirements (e.g., auditor reports or Agreed-Upon Procedures - AUP) apply conditionally to ECB-supervised institutions unless under lump-sum payment; restatements require AUP by...
References SRB's 2026 kick-off letter (Annex 1) and ECB-supervised list (Annex 6 as of 24 September 2025).
Compliance impact
Urgency: High - The 16 January 2026 deadline is imminent (today is 25 January 2026), risking immediate SRB penalties like estimates or maximum risk multipliers if submissions are missed/inaccurate; affects capital planning as contributions directly impact prudential positions.
